Creating a Petabyte HD Array Controlled by a Single Raspberry Pi
Well here’s a Pi project you thought you’d never see. Jeff Geerling created a storage array of 60 20TB hard drives, aka over a petabyte, controlled by a Raspberry Pi 4.
It was just an experiment to see if the Pi had what it took (and to have an excuse to use one of 45Drive’s Storinator XL 60-bay server).
So, did it work? Sorta. Kinda. At least in a proof-of-concept sort of way.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
